Supply checklist

Last reviewed: 10 November 2026

A printable 3-day and 2-week emergency supply checklist for your household of 4 people in Charleston, Dorchester, or Berkeley County, including water quantities and a food-planning method.

For 3- and 14-day water and calorie totals, including pets, use the 3- and 14-day supply calculator.

Print this page and tick what you already have. Quantities are for your household of 4 people unless a line says otherwise. Water uses the official 1 gallon per person per day planning rule from Ready.gov and the Red Cross. Food uses a planning assumption of 2,000 calories per person per day, the general figure on U.S. Nutrition Facts labels (FDA). Needs vary by age and activity; see the USDA ranges.

For the written family plan, see Family plan and checklists. Product links for items on a household emergency-prep list (plain links to several stores, not affiliate links) are on Emergency prep supplies: where to buy.

Household size

4 people
Water, 3 days 12 gallons
Water, 14 days 56 gallons
Food at 2,000 kcal/person/day, 3 days 24,000 calories
Food at 2,000 kcal/person/day, 14 days 112,000 calories

Add water for each pet (see the size-based planning amounts on the 3- and 14-day calculator), and more in extreme heat (Ready.gov notes that needs can double).

Three-day (go-bag and first 72 hours)

  • Water in the amounts above, including some sealed bottles in the bags
  • Three days of familiar, ready-to-eat meals and snacks the household will actually eat
  • Manual can opener
  • Infant formula, baby food, and diapers if needed (ready-to-feed formula if water quality may be uncertain)
  • Pet food, water, leash or carrier, and medicines
  • Prescription medicines for at least 3 days, ideally 7 days, plus a written list of doses and allergies
  • Spare glasses or contact supplies; hearing-aid or device batteries
  • First-aid kit
  • Flashlight or headlamp for each person (4 in all), plus spare batteries
  • Charged power bank for each person who relies on a phone (see capacities on Power and lighting), with the correct cables
  • Battery or hand-crank radio that can receive NOAA Weather Radio
  • Important numbers on paper; document pouch; some cash in small bills
  • Change of clothes, spare socks, rain gear, and sturdy shoes for each person (4 sets)
  • Hygiene items, wipes, soap or sanitizer, menstrual or incontinence supplies
  • Lightweight blankets or emergency blankets
  • Whistle, work gloves, and a dust mask or respirator
  • Comfort item and activities for children

Two weeks at home (in addition to the three-day layer)

  • Water in the 14-day amounts above, in original bottles or food-grade containers, dated
  • Fourteen days of familiar shelf-stable meals, rotated first-in, first-out
  • Optional check: daily calories in those meals compared with the 2,000-calorie planning figure and the USDA ranges for each person
  • Pet food and water for 14 days
  • Hygiene and sanitation supplies for 14 days (toilet bags, bucket with a lid, unscented bleach, soap, toilet paper, wipes)
  • Extra batteries; power banks kept on a charging routine
  • Generator fuel, if you have a generator, stored legally, with a written list of loads you will actually run
  • Blankets or sleeping bags for everyone; a heat and cooling plan
  • Fire extinguisher; smoke and carbon monoxide alarms tested
  • Plastic sheeting, tape, and a utility shutoff tool if appropriate

Twice-yearly review

  • Water dates and quantities still match the household size
  • Food dates; children’s clothes in the bags still fit; seasonal clothes swapped
  • Medicines and batteries in date; power banks charged
  • Documents and insurance numbers updated; some cash still in the pouch
  • Alert sign-ups still work; new phones included
  • Pet records and microchip registration current
  • Walk through the fire exits and the 5-/10-/30-minute evacuation list once
